HP Probook 6570b brightness not adjusting.

[MilFlo]

I have an HP Probook 6570b..

The brightness settings aren't working, if I do Fn+F9/F10 then it should increase the brightness but this one isn't.

If I recall correctly there is a "hotkey driver". But going to HP.com and letting it detect my laptop and list drivers, https://support.hp.com/us-en/drivers I can't see it at the moment.

I have Win10

I notice that for Win7 it has hotkey driver listed. But having installed it, it's not working.

Note- I can use win10 mobility controls brightness adjustm,ent there. And maybe autohotkey could solve it but anyhow. In Win7 there was a "hotkey driver" but it doesn't work on win10.

Thanks, that's exactly it!  The link you give works.

HP have really made an error by not having it on their site!
